PTC Resettable Fuses are a type of electrical protection device specially designed to detect surges in electrical energy and provide a reliable way of protecting equipment. 0ZRE0005FF1C is a PTC resettable fuse which provides protection against overload, short-circuiting and thermal-overload of electric appliances. Its application field and working principle are discussed in this article.

Application Field of 0ZRE0005FF1C

The 0ZRE0005FF1C fuse is widely used in consumer electronics, automobiles, medical equipment, LED lighting equipment, power-on protection of audio and video equipment, communications equipment, computers, digital products, etc. It has a high current interrupted capability and good ability to bear surge current. With its nice temperature characteristics and small size, it is easy to install this device in various electronic circuits.

Working Principle of 0ZRE0005FF1C

The 0ZRE0005FF1C is a Polymeric-type Positive Temperature Coefficient (PTC) resettable fuse. When an overcurrent or overheat occurs, the fuse will melt due to the higher temperature, interrupting the current flow; after the current is interrupted, the fuse will slowly cool down. The PTC resettable fuse will reset itself when the temperature drops down to a certain temperature which is lower than the melting point. This makes it possible for the fuse to protect equipment against damage from overload, short-circuiting or thermal overload.

The operation of the 0ZRE0005FF1C is simple yet effective. The fuse consists of a metal strip which has an adjustable integrated thermistor. When the ambient temperature or the current load increases, the thermistor generates more heat which raises the temperature of the metal strip. When the temperature reaches the melting point, the metal strip will melt, interrupting the circuit and preventing any further increase in current. When the temperature cools down to a certain temperature, the metal strip will reset itself and the fuse will be ready to operate again.

Conclusion

The 0ZRE0005FF1C PTC Resettable Fuses are commonly used to protect equipment against overload, short-circuiting, and thermal-overload. The device is designed with a metal strip and an adjustable integrated thermistor, and is effective in breaking the electrical circuit whenever an overcurrent or overheat occurs. With its reliable protection abilities and small size, the 0ZRE0005FF1C is widely used in various areas.
